Problem

A narrow beam of

100\,\text{eV}

electrons is fired at two parallel slits very close to each other. The distance between the slits is

10\,\text{\AA}

. The electron waves after passing through the slits interfere on a screen

3\,\text{m}

away and form interference fringes. Find the fringe width.
